        摘 要:因氮气物理化学性能稳定,作为环保型气体绝缘介质在气体绝缘开关柜领域受到了重点关注。在目前气体绝缘开关柜常用的非圆柱形电极下对纯氮气分别进行了工频耐压和雷电冲击耐压试验,并对试验结果进行多角度分析,通过曲线拟合得到了较低压力下氮气击穿电压(Ub)与气压和放电距离的乘积(p×d)关系经验公式,研究结果对氮气绝缘开关设备研发具有一定的指导意义。

        Abstract: As an environmentally friendly gas, Nitrogen gas has received close attention recently in the field of gas insulated switchgear due to its stable physical and chemical properties. The power frequency voltage withstand test and lighting impulse voltage withstand test were conducted in lower pressure for the pure N2 gas in non-columniforn electrodes which was commonly used in gas insulated switchgear, and the test result underwent a multi-angled analysis.The curve-fitting method was used to obtain the experiential formula of the relationship between breakdown voltage Ub and p×d in lower pressure. The research result is significant in guiding the research and development of nitrogen
    insulated switchgear.
        Key words: gas insulated switchgear; environmentally friendly gase; N2; insulation performance
